First off yes you can execute one CPU out of onchip memory and another from SDRAM. Or you can execute both of them from seperate onchip memories or both from SDRAM or whatever you want. So that out of the way.

I can't see your system but from your description there are two things I would check first.

1 - Is the debug configuration set up properly for each processor in the NIOS IDE?

2 - Does your second NIOS II CPU have a jtag debug module? If not then it will not be recognized on the JTAG chain and you will not be able to download and execute code to it from the NIOS IDE.
